I was wondering if anyone knows about the SEO impact of using bootstraps visible
classes for creating a responsive website? I have created a new website with Bootstrap using these classes. On most of the pages the main content is on the left and then there are a number of links on the right side of the page. My structure is like this:
<div class="row">
<div class="col-lg-6 col-md-6 col-sm-12 col-xs-12">
//Main content here on left of page
</div>
<div class="col-lg-6 col-md-6 visible-lg visible-md">
//Content on right of page for large and medium devices
</div>
<!--SMALL STARTS HERE-->
<div class="col-sm-12 visible-sm">
//Same content but drops below main content of page for small devices
</div>
<!--EXTRA SMALL STARTS HERE-->
<div class="col-xs-12 visible-xs">
//Same content again but drops below main content and is rendered for phones
</div>
</div>
So my question is if this is a bad idea or not? I am worried that Google/Bing/Yahoo will see this as duplicate content on my pages and penalise me for it. Is this an issue I should be worried about? Thanks.
